SALES TAX CALCULATOR
Wyoming Sales Tax must be paid to the County Treasurer within 50 days of the date of purchase. After 50 days, additional penalties and interest will be due. If you are calculating tax on a sale that occurred more than 50 days ago, please contact your County Treasurer for the amount of penalties and interest due.
New tax rates may change quarterly. The rates calculated above represent those rates. For vehicles purchased in a prior quarter, the rate may be different. Please contact your local Treasurer's Office for information.
